12. FAX Commands
The following commands can be used for fax transmission.
If the ME is acting as a Fax modem for a PC based application (e.g. "WinFax") it is necessary to select the proper
Service Class (Fax Class) provided by the ME. The ME reports its Service Class capabilities, both the current
setting and the range of services available. This is provided by the AT+FCLASS command.
Service Classes supported by the ME:
The following AT commands are dummy commands:
AT+FAA Auto Answer mode
AT+FECM Error Correction Mode control
AT+FLNFC Page Length format conversion
AT+FLPL Indicate document available for polling

AT+FRBC Phase C data receive byte count
AT+FREL Phase C received EOL alignment
AT+FSPL Enable polling
AT+FTBC Phase C data transmit byte count
